X1U

X1U is a modular, open-architecture computing platform designed for embedded and edge applications. It was introduced by NovaTech Systems in 2022 as a scalable base for compact IoT gateways, industrial controllers, and robotics subsystems.

Architecture and modules: The core of X1U is a 64-bit RISC-V base processor with optional DSP and neural-network accelerators. The platform uses a plug-in modular chassis consisting of a base unit, compute modules, memory modules, and I/O mezzanine cards. The design emphasizes high-density compute per watt and interchangeable I/O to support CAN, Ethernet, PCIe, USB, and industrial fieldbuses.

Software: X1U supports multiple operating systems, including real-time Linux and RTOS options. Toolchains target C, C++, and Rust. A reference firmware stack provides secure boot, mechanisms for module authentication, and OTA updates.

Variants and ecosystem: X1U is offered in several variants such as X1U-Base (core compute and memory), X1U-Compute (accelerator-equipped compute units), X1U-IO (dense I/O and fieldbus interfaces), and X1U-AI (AI accelerator module). Third-party partners provide software stacks, device drivers, and development kits.

Applications and reception: The platform targets edge computing, industrial automation, and autonomous devices. It has been noted for its modularity and power efficiency, with some criticism about the size of its ecosystem and the availability of reference designs.
